WAGO-I/O-SYSTEM 750
CANopen
RTC Module
750-640
The above RTC module has a total of 6 bytes of user data in both the Input
and Output Process Image (4 bytes of module data and 1 byte of control/status
and 1 byte ID for command). The following table illustrates the Input and
Output Process Image, which have 6 bytes mapped into each image.

Data bytes
These modules present themselves with 1x6 bytes, so that the object 0x3200
for 6 byte Special Modules, Inputs is used. And the object 0x3300 for 6 byte
Special Modules, Outputs is used. Therefore for each module one Subindex is
occupied.
DALI/DSI Master Module
750-641
The DALI/DSI Master module has a total of 6 bytes of user data in both the
Input and Output Process Image (5 bytes of module data and 1 byte of con-
trol/status). The following tables illustrate the Input and Output Process Im-
age, which have 6 bytes mapped into each image.
